MACHINE FOR STRlPPlNG AND BOOKlNG LEAF-TCBACCO.

SPECIFICATION forming part of Letters Patent No. 504,799, datedSeptember 12, 1893.

Application filed June 19, 1893.

To @ZZ whom it may concern:

Be it known that l, CHARLES BowMnN, a citizen of the United States,residing at Hanover, in the county of York and State of Pennsylvania,have invented certain new and useful Improvements in Machines forStripping and Booking Leaf-Tobacco; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters of reference marked thereon.

The present invention has reference to that class of machines forstripping and booking leaf-tobacco for which a patent was granted to meJuly 26, 1892, No. 479,550, and the invention consists in the severaldetails of construction whereby the stem of the tobacco leaf is securelyheld in position and prevented from lateral displacement while in theact of stripping and the stem fed forward and discharged from themachine, as will be hereinafter described and subsequently claimed.

Figure l of the drawings represents a sectional elevation of my improvedmachine taken on line @om of Fig.2. Fig. 2 represents a sectional planview of the machine taken on line y y of Fig. l. Fig. 3 representsdetail views in perspective of those parts of the machine constitutingmy invention; Fig. 4 a detailview partly in section of the knife rollersand the interposed elastic roller.

In the accompanying drawings A represents a suitable standard or framefor supporting the several operating parts of the machine, the standardor frame being of any preferred form and construction found best adaptedto the purpose. A shaft B has its bearings in the sides of the standardor frame A and has connected to it segmental gears@ between which arelocated the curved tables D, over which pass the flexible booking apronsor bands E connected at their respective ends to rollers F and at theiropposite ends to the frame A or to any other part of the machine. Theaprons operate in the same manner as the aprons in use in my formerpatent and a detail description thereof is deemed unnecessary. Rollers Gare located above the curved tables D and are provided upon their innerends with cutting disks a, said rollers loosely fitting upon a shaft andhave a laterally yield- Serial No. 478,079. (No model.)

ing motion. This yielding motion of the rollers G is attained by thecoiled springs has in my former patent, said spring encircling the shaftof the rollers upon each end thereof.

In describing the construction of a machine of this character, it isdeemed necessary to refer only to such parts in a general way as willenable one to understand the operation, as the several parts hereinreferred to form no part of my invention and therefore may be changed ormodified as found desirable without departing from the principle of myinvention, as it is not essential to the successful operation of themachine that the parts above described should be construct-ed exactly asshown in the drawings but are subject to many changes in theconstruction and arrangement of parts as would be found best adapted tothe purpose.

Between the tables D is located the stemsupport I-I which has a groovedseat c for the stem of the tobacco leaf to rest in and thus prevent itfrom lateral displacement while the leaf is being stripped. The stemsupport H may be provided with lugs as shown in Fig. 3 or other wellknown means whereby it may be connected to the inner ends of one or bothof the tables D by means of screws or bolts or other like fastenings, orit may be connected in any desirable manner to any lixture of themachine so that it will be held stationary between the tables. Thegrooved seat of the stem-support is formed tapering to substantiallyconform to the gradual taper of the stem, this thickest part thereofresting in the widest portion of the grooved-seat.

To form a guide for the stem of the tobacco-leaf I provide a guideroller I which is located over the stem-support H, said roller beingelastic so as to yield to the irregularities in the thickness of thestem, the surface of said roller being either plain as shown or groovedas found preferable. The guide roller I which forms a guide to the stemwhile the leaf is being stripped, is suitably connected or supportedupon a shaft f, which shaft has its bearings in the frame of themachine. The side of the stem-support H has cutting edges g whichtogether with the cutting-disks a produce a shear cut in severing theleaf from the stem.

Between the inner ends or sides of the cut- IOC ting-disks a is locatedan elastic roller .I which 1s supported upon the same shaft thatsupports the rollers G. This elastic roller J which may have a plain orgrooved surface, acts with the cutting-disks and holds the stem of thetobacco leaf while it is being separated therefrom and assisting thestem to the .short track Za upon the chute L. The stem as 1t is severedfrom the leaf passes under a feeder K which has radial feeding blades7l, and as the feeder rotates, it will force the .stem forward over thechute L from whence 1t is discharged into a receptacle or deposited uponthe floor. The feeder has motion irnparted to it through the medium ofthe gear Wheel t' meshing with the teeth of the segmental gear C.

The machine may be operated by a foottreadle M or by any other suitableand well known means. The track lo of the chute Lis located on line withthe grooved seat e so that when the stem passes from the grooved seat itWill ride over the track and ont-o the chute Where it is fed forward bythe feeder hereinbefore described. The cutting disks a have theircentral portion cup-shaped so as to form seats for the ends of theelastic roller J as shown in Fig. 4.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

l. In a machine for stripping and booking leaf-tobacco, a grooved seatfor the stem of the tobacco-leaf, and a guide roller and rollers havingcutting disks located over it, substantially as and for the purpose setforth.

2. In a machine for stripping and booking leaf-tobacco, a stem supporthaving a'taperhaving radial feeding blades, substantially as and for thepurpose set forth.

5. In a machine for stripping and booking leaf-tobacco, a stem supporthaving a grooved seat, an elastic guide-roller located over the seat,suitable cutting disks and an elastic roller located between thecutting-disks, substantially as and for the purpose set forth.

6. In a machine for stripping and booking leaf-tobacco, a stem supporthaving a grooved seat, an elastic guide-roller located above it,suitable cutting disks and leaf supporting means an elastic rollerlocated between the cutting-disks, a chute having a short track on linewith the grooved seat, and a feeder located over the chute,substantially as and for the purpose described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
